My invention relates to repeating air guns or pistols and more particularly to an air gun of the said character having a ymovable magazine for projectiles which is automat- 'i 5 ically fed upon operation of the cocking mechanism. o

l rllhe main object of my invention is to provide a particularly advantageous conv struction and arrangement of the magazine,

so that both spherical bullets, and, if desired or preferred, cylindrical projectiles orsocalled diabolo-projectiles may be fired, and the invention consists essentially in constructing and arranging the magazine on the barrel over and above the axis of the bore thereof .in a manner that the several chambers or pockets of the magazine receiving the single projectiles, will be adjustable over or with relation to the aperture of a charging valve provided in the barrel for the pur- `ppse of transferring the projectiles singly expedient.

In the accompanying drawingsforming a lpart of this specification and showing, as above stated, for purposes of exemplication onlyz a preferred form and manner in which the invention may be embodied and' practised, but witho t limiting the claimed invention to such i ustrative instance zy Figure l1 represents a side elevation of that portion of an air yrifle constructed accordin to the present invention, to which the invention relates, with the air-plunger in its frontal end position or position of rest; Eigu thereof with thev air-plunger in an intermediate yposition and the correspondingly displaced cocking lever, the cocking .bar and other co-operating members shownin dotted re 2 is a view in longitudinal section.

lines. Figure 3 is a view in top plan of the same with the magazine filled with bulletsA and the cover plate thereof so turned that the filling or show apertures thereof are displaced with relation to the pockets of the magazine and the bullets thus are prevented from escaping therefrom accidentally: Fig'- ure -i is a view similar to Figure 3, but with the cover plate removed from the magazine, so that the inner construction thereof, especially that of the charging pockets and the feeding mechanism are exposed; Figure 5 is a view in top plan of the charging valve; and Figure 6 is a side elevation thereof.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The barrel 1 is rigidly connected or integral with thecylinder 2 forming. the air chamber and enclosing the air-plunger 3 in the usual manner so that the latter is adapted to be displaced towards the rear end of the cylinder or air chamber and forced towards the front end thereof by the main spring 4.

Mounted in the plane of the bore of the barrel and transversely thereto at a point near the rear end of the barrel is a charging valve 5 having a conical bore 33 in a vertical plane coinciding with the vertical plane of the bore of the barrel, the front or bottom end of the bore 33 which is somewhat narrower than the rear or top end thereof, being of a somewhat greater diameter than the bore of the barrel. The charging valve 5 is adapted to be turned and firmly connected, at its lefthand outer end, with a two-armed lever whereof the longer front arm 6 is pivoted to a link 7 while the' shorter rear arm 8 thereof, is provided with a bore for the accommodation of azfeeding pin 9 equipped with a coiled A spring lOencircling the same, and .a screw 11 in its oneend as will be seen in Flgure 5.

The link 7 is pivotally connected with the cooking lever 13 by means of a screwiv ot 12 so that when the lever 13 is moved an dlsplaced for about' 90 the chargin valve 5 will also be positively displaced or or from its horizontal position, as shown in Figure 1, to a, vertical pom'tion, not fully shown in Fi T2, or vice versa. The'cocking lever 13 is dlsited to rotate about the pivot 14 and pivotally attachedto the cocklng bar or scar 16 by means of a pivot 15. When the cockmg lever 13 is manually moved downwards or off the barrel 1, a's shown in Figure 2, the scar 16 connected with the plunger 3 in the usual manner,'will act to force the plungerinto the cocked position.,

e tainer or magazine 17, properly speaking(i and Mounted on the rear end of the barrel in a plane parallel to the horizontal plane of the boreis -aI magazine comprising a stationary bottom plate 21, -a revoluble cylindrical cona cap or cover 24. The magazine 17 is a apted to revolve about a vertical stud 18 rigidly connected with the barrel and provided 'with a number of peripheral chambers or vpockets 19 for the reception of a corresponding number of projectiles. The periphery of the magazine 17 is serrated and the number ofthe marginal teeth 20 thus produced corresponds tothe number of 'pockets 19. The revohlble tile to drp into the valve bore, as Awill be readily un' The cover plate or cap 24 is pivotally attached lto the stud 18 by means Vof a screw 25 so as to cover and laterally enclose the ma ine 17 in concentric superposition' witazrelation to the latter. The plate orA cap 24, however,- is adapted to revolve for `a small ran lof aboutone half of the diameter of -a'proJectile only, suitable stops, abut-- ments or notches and an arresting pin 26,be'

ing provided for arresting the cap 24 in the two-end positions of the said revolving range.

, Tothis end the pin 26 is movably housed in or point thereofto e Y a slanting boreof the rear' end of the barrel and supported therein by a coiled ring 27 tending to force the pin 26 out of t e slanting vbore and hereby 4causing the outer end ge in the one or the other one of two no es 28 provided in the vperi heral surface of the cover or cap 24.

with the into the jectiles .through the pockets 19, whereupon e cap 24 is turned in clockwise direction as far as to be arrested by the second stop or abutment. The extent or range of they angular movement of the cap 'is determined by the distance between the two stops or abutmcnts and amounts, in the common circular centre line of the openings 29, to about one halfof the diameter of .the openings 29, or the pockets 19 only so that when the cap has been turned clockwise direction to the end of its moving range, the pockets 19 and theprojectiles therein will be or' lie partially covered by the cap, as shown in Flgure 3, and the projectiles be prevented from dropping out of the pockets 1 9 upon turning the riie upside down.

The outer surface'of the annular part of the cap is knurled to afford a better grip. The springy rings and 31 surrounding the stud 18 are adapted to contact'with and exert a slight pressure against the cap 2 4, but the main purpose of Athe rings resides. in the braking action they exercise upon the magazine in order that the latter be lprevented enings 29`into theY from accidental on automatic feedlng movements.

In the embodiment shown the magazineis of cylindrical or drum shape. Obviously the other appropriate conliguration and may be d 1n inclined position, that is at an angle to the axis of the bore of the barrel, instead of parallel vthereto .as shown. Furthermore, there may be provided mechanical means for operating the magazine vby means of spring action or loo the like inconnection with a releasable ratchet pawl, in lieu of operating the same manually as in theembodimentillustrated and described.

' When vthe magazine 17 has been supplied with rojectiles andthe capy 29 has been turne in clockwise direction in themanner hereinbefore described, so that the pockets 19 and the rojech'les therein are partially covered, t e char of the riie for the firing purpose is e ected in the followmg manner.

The cooking lever 13 is swung by'han'd to the rear whereby the charging valve '5 will be turned for v through the. agency of the `link 7 andthe Yvalve lever 6, 8 ivotally connectd therewith.-

Simultaneously with the rotation of the charging valve 5 the feeding 1n 9 of the short arm'8,o f the -valvele've'r 1s operated to feedthe of one tooth correspondingl to the angular length of one'pocket 19, in order that the I irst pocket he brought into verticallalinenientwiththe bore33.

The described manipulation of the cocking lever is repeated, upon tiring a shot, for aV next discharge and so on until the magazine is emptied.
